TL3116IDR

Comparators Overview

The TL3116IDR is a single-channel ultra-fast precision analog comparator manufactured by Texas Instruments. It operates from a single 5-V supply or dual ±5-V supplies, drawing a typical positive supply current of 12.7 mA. The device features a propagation delay of 10 ns (typical) and an input offset voltage of 3 mV (maximum). It provides complementary push-pull outputs capable of interfacing directly with TTL logic. The component is housed in an 8-pin SOIC package and supports an operating temperature range of -40°C to +85°C.

Comparators Feature Summary

• Ultra-fast operation with low propagation delay for high-speed signal processing
• Precision performance characterized by tight input offset voltage specifications
• Complementary output configuration enabling direct interface with TTL logic circuits
• Input common-mode voltage extends to the negative rail for ground sensing applications

Comparators Applications

• Ground sensing applications requiring negative rail input capability
• High-speed signal processing circuits demanding fast response times
• Interfaces connecting analog signals directly to digital logic gates
• Precision threshold detection systems utilizing low offset voltage characteristics

Comparators Procurement Notes

Verify the specific ordering suffix 'IDR' corresponds to the active production status and SOIC-8 tape-and-reel packaging format. Confirm that the industrial temperature grade (-40°C to +85°C) aligns with your environmental requirements. Ensure compatibility with the specified single or split power supply configurations during system design validation.

Comparators Selection Notes

Select this component when high-speed switching and precision are required within a single-channel architecture. The device offers a functional replacement for legacy LT1116 comparators while consuming significantly less power. Consider the complementary output structure if both true and inverted signals are needed without external inversion circuitry.
